HOSE CLAMP.

Application filed September My present invention relates to improve- *Illllliii in hose clamps designed especially for use in connection with garden hose for the purpose of malrin g \i'ater tight or sealed joints as between the hose-and a nipple or sleeve.

The primary object ofthe inventionis the provision of a hose clamp of the wrap around type which. performs its function similar to a snubber or friction device, and ineans are provided for clamping or tightening the wrapped portion of the hose clamp in order that the joint may be effectively sealed and made water tight.

In carrying out my invention, I utilize sheet pressed to shape and these blanks are fashioned to circular form in order that they may be wrapped around the hose, and their free ends connected for the purpose of clamping the device so on the hose. 1

In the accompanying drawings, I have illustrated several forms in which my invention is embodied, such forms or modifications showing the best modes I have so far devised for the practical application of the principles of my invention.

Figure 1 is a perspective view of a hose clamp using a clamp bolt threaded into a clamp plate, and showing the hose clamp in 30 operative position;

Fi 2 is a perspective view of a hose clampshowing a stud bolt, clamp plate, and clamp nut on the bolt for tightening the hose clamp about the hose;

3 is a perspective view showing a modified form of the device illustrated in Fig. 1

Fig. f is a sectional view through a hose joint showing the clamp plate with the clamp bolt passed therethrough, the plate being permanently attached to one end of the clamp and detachably connected to the other end;

Fig. shows a clamp plate detachably con nected to both ends of the clamp, and using a stud bolt and nut for clamping;

Fig. 6 is a perspective view of the metal blank before it is fashioned as the hose clamp Fig. 7 is a perspective view of a hose clamp using a slot construction and a locking tongue for coaction therewith;

Fig. 8 is a side View of the clamp of Fi 7; and

Fig. 9 is a perspective view of the blank before it is fashioned into the hose clamp of Fig. 7.

In Figs. a and 5, in order that the general cated in Figs. 1, 3 and 4.

engage in transverse slots 2, 1927. Serial 21032173368;

assembly and arrai'igement of parts may readily be understood, I have shown anipple as N and a hose. as H in section with the hose clamp secured in operative position. I i

.In Fig. v6, the metal. blank is shown'as stamped 01" pressed from sheet metal and comprisinga metal plate as 1 having at one end a head 2 and u transversely extending slot 8therein. The plate is fashioned. with 'two narrow portions 4 and 5 extending; from the wide central portion 1 of the plate, and the narrow strip 5 which is about one half the Width of the plate, is fashioned with a head 6 that is adapted to be folded on a transverse line between thetwo rivet holes 7 in the head The head 6 is adapted to be folded over to reinforce and strengthen the hose clamp, and a log or foldable tongue 8 is provided on the head for a second fold around the head to further strengthen the folded head, as indicated in Figs. 4 and 5 which show the folded over heads and the lugs 8 inside of the respective ends of the recess or depression 9 with which a bolt 10 is adapted to coact, and this bolt in Figs.

1, 3 and 4 is threaded through an arched clamp plate 11. This clamp plate, at one end, is riveted at 12 through the holes 7 as indicated in Figs; 1, 8and 4, and this end of the clamp plate is rigidly secured to the head 6 of the clamp. A tongue 13 on the free end of the clamp plate is adapted to slip into the transverse slot 3 in the head 2 at the opposite end of the hose clamp as indihus it will be seen that the hose clamp is fashioned as a complete circle With its two ends joined by the clamp plate. One. end of theclamp plate is permanently secured to one end of the hose clamp, and the other end of the clamp plate is detachably connected to the other end of the hose'clamp. It will be apparent that by turn- 'ing the bolt 10 in the clamp plate, the circle of the hose clamp is reduced in diameter, and the clamp is thus tightened on the hose as indicated in Fig. 4:.

In Figs. 2 and 5, the clamp plate 14 has upturned ends 15 and 16, and these tongues in the heads 17 and 18 of the hose clamp. A stud bolt 19 is fixed to the body of the hose clamp, and a flanged nut 20 is threaded on the bolt and located in an opening in the clamp plate 14. A clamp nut 21 is also used on the stud bolt 19 above the clamp plate 14, and it will be apparent in Fig. 5 that by turning the nut 21 and the nut 19, that the diameter of the circle of the hose clamp is reduced to tightly grasp the hose.

In the form of the device shown in Figs. 7, 8 and 9, I use a metallic plate 22 which has a longitudinal slot 23, and an extension 24 01 this plate or band 22 is adapted to pass through the slot 23. Thus, the plate is formed a circular band with the extension 2% passed throu 'h the longitudinal slot 23 and on the end or the extension 24- is secured a head 25 which is rigid with the end of the extension 24, and a screw 26 passes through .the head and the end of the extension as by turning the bolt or screw 26 the circular manently secured to one end 01 the band, means for detachably securing the clamp plate to the other free end of the band, and a clamp secured in the clamp plate for reducing the diameter of the circular band.

2. The combination in a hose clamp fashioned as a circular band with a double turn and free ends, of a clamp plate permanently attached to one of said ends, a tongue on said plate engaging a slot in the other end, and a clamp screw threaded in said plate'for reducing the diameter of the circular band.

In testimony whereof l affix my signature.
